Julian,
No, you should not change the myCell(1, 13) part of the code.
The myCell(1,13).Value means to pick up the value from the same row as the
name currently being processed, out of the 13th column (M)
There are many ways to address ranges or cells in Excel. I could have
referred to that cell by using:
myCell.Item(1,13).Value (myCell(1,13) is a shortcut for the Item property)
Worksheets("Balances").Cells(myCell.Row,13).Value
Worksheets("Balances").Range("M" & myCell.Row).Value
myCell.Offset(0,12).Value
The advantage of using myCell is that defined range objects don't require
the worksheet to be identified since they are associated with a specfic
worksheet.
But that's too much for a beginning coder to learn or need to know - just be
happy if you get the code to work.
HTH,
